Answer: a) x 1.04

b) x 0.94 = 150.4

Step-by-step explanation:

a) find 4% of 160 = 6.4

160 + 6.4 = 166.4

166.4/160 = 1.04 therefore you multiply by 1.04

b) find 6% of 160 = 9.6

160 - 9.6 = 150.4

150.4/160 = 0.94 therefore you multiply by 0.94 which then equals to 150.4

Answer:

To decrease 160 by 6% you have to do 160×.06 and you get 9.6. then you do 160-9.6 and you get 150.4

Help plz...................................

N76 [4]

Answer:

Step-by-step explanation:

These are similar triangles, so the ratio of their sides is the same for each side.

AB = 8 and BD = 10

So, the ratio is 8:10 or 4:5

Because the triangles are similar....

The ratio of AC:CE is also 4:5

12:15 = 4:5

So, 12 is the answer!

Sort each equation according to whether it has one solution, infinitely many solutions, or no solution.

Sedaia [141]

Answer:

Equations with one solution: $-2(x-3) = 2x-6$

Equations with no solution:

$6(x+5) = 6x+11\\5(x-2) = 5x-7$

Equations with infinite many solutions: $-3(x-4) = -3x+12$

Step-by-step explanation:

We will solve each equation to see if it has one solution, no solution or infinite many solutions.

An equation where the value of variable can be found has one solution.

An equation with no solution has both sides different.

An equation with infinite solution will have both sides equal after solution(number)

So,

Equation 1:

5(x-2) = 5x-7

$5(x-2) = 5x-7\\5x-10 = 5x-7\\5x-5x = -7+10\\0 = 3$

As both sides are not equal, equation has no solution.

Equation 2:

$-3(x-4) = -3x+12\\-3x+12 = -3x+12\\-3x+3x = -12+12\\0=0\\$

As both sides are equal the equation has infinite many solutions.

Equation 3:

$-2(x-3) = 2x-6\\-2x+6 = 2x-6\\-2x-2x = -6-6\\-4x = -12\\\frac{-4x}{-4} = \frac{-12}{-4}\\x = 3$

As x=3, the equation has only one solution.

Equation 4:

$6(x+5) = 6x+11\\6x+30 = 6x+11\\6x-6x+30 = 11\\30 =11$

The equation has no solution.

Hence,

Equations with one solution: $-2(x-3) = 2x-6$

Equations with no solution:

$6(x+5) = 6x+11\\5(x-2) = 5x-7$

Equations with infinite many solutions: $-3(x-4) = -3x+12$
